No single test diagnoses Down syndrome — it is genetic. In early childhood, clinicians use a multidomain battery: norm-referenced developmental scales (Bayley, Griffiths), adaptive measures (Vineland), language tools (PLS, CDI) and motor/feeding observation, scaffolded by CDC/AAP milestone surveillance, with serial re-assessment to track progress.

*A child with Down syndrome is best understood not by a single label but by a developmental profile — and the right tools turn that profile into a plan.*

## In short
Assessment of a child with Down syndrome in early childhood is **multidomain and serial**, not a single test. Clinicians typically pair a norm-referenced developmental measure (such as the **Bayley Scales of Infant and Toddler Development**) with adaptive-behaviour and communication tools, alongside structured motor and feeding observation. The aim is to map functioning across cognition, language, motor, social-emotional and self-care domains — establishing a baseline to track over time, not to confirm the diagnosis, which is genetic.

## The science — tools by domain
- **Global development / cognition:** Bayley Scales (Bayley-III/4) and the Griffiths Mental Development Scales give norm-referenced developmental quotients.
- **Adaptive behaviour:** Vineland Adaptive Behavior Scales (VABS-3) capture everyday functioning across communication, daily living, socialisation and motor skills.
- **Language & communication:** MacArthur–Bates CDI, Preschool Language Scales (PLS-5), and clinician speech-language profiling — vital given the expressive-language and oromotor profile common in Down syndrome.
- **Motor & feeding:** Peabody Developmental Motor Scales and structured feeding/oromotor observation.
- **Surveillance scaffolding:** CDC *Learn the Signs. Act Early.* milestones and AAP/IAP-aligned developmental surveillance frame when to re-measure.

Because progress in Down syndrome is steady but individual, **serial re-assessment** matters more than any single score.

## The Pinnacle way
A clinical **AbilityScore®** — and any diagnosis — is established only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or online form. Our clinician-administered structured assessment consolidates these domains into one trackable baseline.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
